Application filed February 21, 1916.

To all whom t may concern:

Be it known that I, MELvILLn CLARK, a citizen of the United States,residing at Chicago, in the county of Cook and Stater of Illinois, haveinvented new and useful Improvements in Drive Mechanism forCombinedwPhonographs and Player-Pianos, of which the following is aspecification, reference being had to the accompanying drawings, forminga part thereof.

The purpose of this invention is to combine in a single casing aphonograph mechanism and a` player piano mechanism, and-to arrange fordriving the phonograph from the same motor which drives the take-up rollof the player mechanism. The invention consists in the features andelements of construction contributing to this result and theircombinations described and shown in the drawings as indicated by theclaims.

It may be understood that this combined phonograph and player piano isdesigned primarily for rendering vocal or instrumental selections bymeans of the phonograph with piano accompaniment controlled by the.usual form of perforated note sheet, shown at 1, in Fig. l; the rotaryrecordcarrving table of the phonograph is arranged to be driven at auniform speed from the same motor shown at 2, as is regularly providedfor driving the take-up roll, 3, of the player mechanism. In order,however, that either the player piano or the phono,- graph may beoperated independently when desired, it is necessary to make theydriving conneetionssuchthat either mechanism can be driven alonefrom-the motor, 2.

This motor, 2, may beV of any convenient type fitted with aspeed-regulatingv governor and speed-varying.means ;-it isshown in thedrawings as a spring motor of substantial construction, and to renderits relation to the other partssufliciently clear it musty be describedsomewhat in detail.V Referring to Figs. 11, 12, 13 and-14:, it will benoted that the motor is mounted just beyond the casing carrying thetake-up` roll, 3. Its spring drum, 2, is geared to a small pinion, 2b,on

the shaft, 2C, carrying a gear, 2d, meshing with a pinion, 2e, on theshaft, 2f. From this shaft motion is transmitted through spiral gear.-ing to the so-called fly-ball or centrifugal governor whose mode ofoperation is well understood and Iwhose friction disk, 2g, is engaged bya brake, 2, whose adjustments serve to'eontrol the speed-,of the motor.The shaft, 2f,-also carries a gear, 21, meshing with a gear, 2k, whichis carried-on an arm, 21, mounted to swing about the axis of the shaft,2f, connecting the gear, 2, either with the gear, 2m, on the take-uproll shaft or with the gear, 2, for driving the pinion, 2, on therewindv shaft. The brake, 2h, is carried by one arm offa bell cranklever,2q, whose other arm engages a cam slot, 2r, in a slidable controlbar, 2S. whose movement ina direction parallel'to the axis of thetake-up roll, 3, effects the-,adjustment offthebrake, 2h, for. varyingthe speed of the mOtor, 21, andv even for holding it at rest. A secondcam slot, 2t, inthe bar, 2s, controls a bell crank,y 2, connectedbyfalink, 2U to the Patented Nov. 13,1917.

swinging arm, 21, which carries the gear, 2k, so that after the cam bar,2S, has been moved from its Zero speed position to its maximum speedposition by means of a hand lever, 2W, a further movement of the leverin the same direction shifts the gear, 2k, through its neutral positionand inte mesh with the gear, 2, for rewinding the note sheet with themotor running at maximum speed.

Now referring to Fig. 2, the record-carrying table of the phonographwill be found indicated by a dotted circle at, 4, and the spindle ofthis table is shown in section at 5, carrying a friction pulley orwheel, 6, whose periphery contacts with the face of the friction plate,7, secured to the end of a shaft, 8, at whose opposite end a spurpinion, 9, mounted near the adjustable journal, 10, of the shaft, 8,sta-nds'in position to mesh with the gear, 2d, on the motor, 2. As aboveindicated, this gear is normally connected in the train which draws thetakeup roll, 3, but since the phonograph table, s'-, must be operated ata constant speed to avoid varying the pitch of the music produced, andsince it may be necessary from time to time to slightly vary the speedof the take-up roll, 3, for synchronizing the phonograph music with theplayer accompaniment, it is no longer feasible to drive the take-up rolldirectly from the motor 2, when both mechanisms are to be operated bysaid motor, and motion is, therefore, transmitted to the take-up roll,3, through a pinion, 11, on the shaft, 8, meshing` with a gear, 12,whose face, 12a, constitutes a friction plate in driving engagement witha friction wheel, 13, rotatively carried on a shaft, 14k, but slidablelongitudinally thereof for varying its position on the face of the gear,12, and thus varying the speed transmitted. The shaft, 14, carries abevel gear, 15, meshing with a similar bevel gear, 16, on a horizontalshaft, 17, provided with a disengageable clutch, 13, connecting with thetake-up roll, 3.` A yoke, 19, engaging the grooved hub of the frictionwheel, 13, and carried on a slidably mounted stem, 19a, is arranged tobe shifted through a bell crank, 20, and links, 21, by means of ahandle, 22, which is accessible just below the take-up roll in thecentral open panel of the piano casing.

As to the operation, it may be understood that the governor brake, 2h,of the motor, 2, is first utilized for varying the speed of thephonograph table, it, to insure that the phonograph record will berendered in correct tune with the `piano. Then by pressing the knob, 23,on the rod, 23, the latch member, 24, is depressed to release the lowerend of the bell crank, 25, permitting its upper and horizontal arm, 25a,to swing downwardly and lower the stylus, 26, onto the phonograph recordindicated at 27, in Fig. 3.

With the record standing at rest the stylus, 26, is placed approximatelyat the point at which the actual music begins, and the arm, 2.3, of thebell crank, 25, is then raised to lift the stylus, 26, just off therecord, 27, i

the bell crank, 25, being retained in its position by the latch member,2i, which automatically resumes the engagement illustrated in Fig. 3under the tension of its spring, 2S. A small motor pneumatic, 29,connected to the lower end of the rod, 23, and thereby linked to thelatch member, 211'-, is adapted to release the latch, 211, whencollapsed, thus permitting the sound box, 30, and its stylus, 26, to belowered by gravity onto the record, 27. Fig. (i illustratesdiagrammatically the motor pneumatic, 29, connected with its primarypneumatic,'31, which is connected to a duco2. in the tracker board, 33,so that if. the perforated note sheet which is to control the playing ofthe piano accompaniment to the phonograph music be provided with aperforation positioned to uncover the duct, 32, at the proper point inthe accon'ipaniment for the beginning of the phonograph music, the notesheet will serve to automatically bring the phonograph into action bythus actuating the motor pneumatic, 29, which releases the latch member,21, and permits the stylus, 26, to engagethe record, 27. Afterascertaining the correct speed for proper timing of the phonograph musicand finding the proper initial position for the stylus, 26, the motor,2, is first started at the ascertained speed and begins to revolve thetable, 1l, and also the take-up roll, 3, driven through the medium ofthe friction wheel 13, engaging the face of the gear, 12; the notesheet, 1, being advanced by the rotation of the take-up roll, 3, andhaving an aperture register-iu g with the duct, 32, then automaticallystarts the phonograph music, and the operator can almost .immediatelynote whether the accompaniment should go slower or faster to be properlysynchronized with the phonograph solo. Such synchronization is easilyeffected by shifting the friction wheel, 13, by means of the handle 22.

nlthough the perforated note sheet is especially cut to serve forcontrolling an accompaniment to a particular phonograph record, beingpreferably made by the automatic recording of the hand-playedaccompaniment of a competent artist, the lengthening or shortening ofthe paper note sheet, due 'to changes of hinnidity, may require thatoccasional adjustment of the speedcontrolling handle be made during therendition of the piece to keep the accompaniment strictly synchronized.In addition to such changes of speed it may be desirable to arrange fortemporarily varying the ratio of speed between the note Sheet, 1, and

the phonograph record, 27, and this may be effected automatically bymeans of a familiar' step-by-step device, shown in detail in my PatentNo. 1,013,862, dated Jan. 9, 1912, and indicated in Fig. 3 at 34. Thisdevice includes a rack, connected by a` link', 36, to the bell cranklever, 20; a gear, 37, meshing with the rack, 35, is arranged to be fedstep-by-step in one direction by a motor pneumatic, 38, and similarly inthe opposite direction by the pneumatic, 39, said pneumatics beingcontrolled, respectively, by ducts, 40 and 41, as indicated in Fig. 6.

Since the note sheet controlling the accompaniment is especially made tofit the particular phonograph record, 27, there will be a particularpoint in the note sheet corresponding quite accurately to the last noteof the phonograph music, and immediately following this point the notesheet may be perforated at a position to register with a duct, 42,controlling the primary pneumatic, 43, corresponding to a motorpneumatic, 44, which is connected by a link, 45, to the lower end of thebell crank, 25, so that collapse of motor pneumatic, 44, will draw thelever, 25, back into the notch of the latch member, 24, in whichposition it will be retained, and in moving to which position it willraise the stylus, 26, out of contact with the record disk, 27, and thusthrow the phonograph out of action.

Now if it is desired to operate the player piano mechanism without thephonograph, the phonograph mechanism is disconnected from the motor, 2,by slightly springing the shaft, 8, out of line far enough to disengagethe teeth of the pinion, 9, from the teeth of the gear, 2d. This is doneby shifting a cam lever, 46, mounted on the side wall, 2X, of the motorcasing to a position in which its notch, 46a, enga-ges the pin, 47, ofthe slidably mounted journal bearing, 10, for the shaft, 8, and thenotch, 46, being at the high point of the cam, it will be evident thatthis movement serves to separate the pinion, 9, from the gear, 2d. Thenotch, 46a, is only a slight depression in the face of the cam, butsufficient to retain the parts in this adjusted position.

The shaft, 8, being thus thrown out of service, the take-up roll, 3, canno longer be driven through the clutch, 18. The slidable member of theclutch, 18, is connected through a shifter rod, 49, with the slidablemember of a clutch, 50, on the shaft of the motor gear, 2, so that asthe clutch, 18, is disengaged the clutch, 50, serves to couple the shaftdirectly to the take-up roll, 3, and the movement of the shifter rod,49, is effected by a slidable cam block, 51, connected directly to thecam lever, 46, as shown in Fig. 4. A follower roller, 52, on the end 0fthe shifter rod, 49, engages the cam face of the block, 51, as indicatedin Fig. 5, and is maintained in such engagement by a spring,conveniently disposed near the opposite end of the rod, 49, to reactagainst the one wall, 53, ofthe tracker housing, 53. A link, 54,connected at one end to the cam lever, 46, and carrying at its oppositeend a handle, 55, projecting through a slot in the wall, 53h, of thetracker housing, provides the manually engageable adjusting means forthe cam lever, 46, and sliding cam, 51. It will be clear from Figs. 4and 5 that when the lever, 46, is moved to the middle position of itsrange, that is, with the pin, 47, engaged in the notch, 46, the followerroller, 52, will ride on the highest part, 51, of the cam, 51, thuseffecting crowding engagement of the clutch, 50.

dien the player piano is operated without the phonograph, it may bedesired to use upon it such perforated note sheets as are provided forautomatic control of the tempo by means of perforations positioned toregister with the ducts, 40 and 41. Such perforations would effectactuation of the stepby-step device, 34, as fully described in my saidPatent No. 1,013,862 and to render this operative for controlling thetempo there is provided a hook, 56, designed to engage an eye. 57, forconnecting the link, 21, directly to the motor governor whosecontrolling lever is rigidly associated with the movable tempo index,58, on which the eye, 57, issecured. This detail is shown in Fig. 7,

though the connection between the index,

58, and the governing devices of the moto'i, 2, are illustrated indetail in Figs. 11, 12, 13 and 14. But since the movement. of the link,21., necessarily involves movement of the bell crank, 20, and with it ashifting of the friction wheel, 13, across the face, 12a, of the gear,12, it is desirable to separate the frictionally engaged surfaces of thewheel, 13, and gear, 12, and this is automatically effected by a camroller, 59, carried by the cam lever, 46, in position to encounter oneend of a tubular thrust link, 60, slidably mounted on the shaft, 8, andconnected by a lever, 61, with a push rod, 62, arranged to act againstthe center of the face of the gear, 12, to push said gear axially out ofengagement with the friction wheel, 13, by slightly compressing itsfollower spring, 63. Since the push rod, 62, only comes into play whenthe shaft is disconnected from the motor, 2, the gear, 12, stands idleand is in no way embarrassed by the action of the push rod, 62, and thefriction wheel, 13, is left free for sliding movement following themovement of the link 21.

Then it is desired to operate the phonograph alone and independently ofthe piano, the handle, 55, is moved through the entire range bringingthe pin, 47, into engagement with the notch, 46", of the cam lever, 46.This vpermits thegear, 9, to move back into mesh with the gear, 2d, foroperatively connecting the motor, 2, With the phonograph table, et.Simultaneously the cam member, 51, is shifted to bring its surface, 51h,into contact With the follower roller, 52, on the shifter rod, a9, andsince this surface, 51h, is in a plane intermediate the planes of thesurfaces, 51 and 51, respectively, it puts the shifter, 4H), into aposition in which both the clutches, 1S and 50, are disengaged from thetake-up roll, 3, so that the motor, 2, causes no movement of the take-uproll, 3. From this position of the cam lever, 46, the cam roller, 59, iscarried below the shaft, 8, and beyond the end of the tube, 60, thereonallowing the latter to stand in its normal position With the thrust rod,62, exerting no pressure on the face of the gear, 12.

vWhen the motor, is a spring motor it is normally kept Wound byautomatic Winding devices, not shoivn, and connected with the pumpingmechanism of the player piano, but when the phonograph is used for anyconsiderable length of time Without the player mechanism of the pianothe spring motor will of course run dovvn and must be reivound. Sincethe Winding shaft, (5f-it, extends to the end of the piano casing at 65,for convenient connection of the Winding clutches, 66, With the pumpingmechanism in the loiver part of the piano case, it is a simple matter toprovide reduction gears, 67, 68' and 69, connecting the Winding shaft,G4, with a short shaft, 70, and a emovable Winding crank, 71, justoutside the end panel, 65, of the piano case.

As indicated in Fig. 3, the sound box, 30, of the phonograph connectsthrough its tone arm, 72, With an amplifier, 73, opening directly intothe back of the frame ivhich carries the take-up roll and note sheetspool. The sound-discharging opening, 7a, is arranged to be varied as toits size for controlling the volume of sound discharged therefrom byprovision of a curtain, 75, shoivn mounted on a roller, 76, and carryingin its free end a Weighted rod, 77 Whose ends are guided in guideivays,78, While the roller, 76, is arranged to be rotated through a train ofgears indicated on Fig. 3 at 7 9, and manually operable through ahnurled knob, 80, conveniently located near the front of the frame andin the opening into which the note sheet spool is to be mounted.
